T0 ALL WHOM IT MAY CONCERN:

Be it known that I, .CHARLES A.,WINN, of Lockhaven, in the county of Clinton., and 'Stateof Pennsylvania, have inventedaI new and improved Brick-Machine; and I dov hereby declare that -the following is a full, clear, and exact description thereof, reference being had'to the accompanying drawings, and the letters of reference marked thereonrin'which-v v A i Figure 1 represents a front elevation ofthe machine, partly'in section.

Figure 2 represents a verticaltransverse section of the same, and` Figure 3 a plan or top view of the same, partly in section.

, Similar letters ci" reference indicate the same parts.`

p The nature of my invention consists in constructing, on wheels, or otherwise, a clay-mill, steam-boiler,

cylinder, and pump, so combined as' to form in themselves one complete and portable apparatus for the manufacture-of bricks, and the introduction of heat, steam, and hot water to the clay-mill in such a manner, and in conjunction with knives or kneaders,"s0 arranged as to thoroughly temper, disintegrate, and prepare the clay for moulding.

To dothis, I construct my boiler with a suitablesteam-cylinderand pump on a portable bed, with a. verti'` cal or other clay-mill fitted directly upon the b oiler. Through the clay-mill I x a shaft, which` receives a rotary motion by suitable connection with the'steam-cylinder. This shaft is provided with knives and kneadn ers, to knead and stir the clay, and the usual scroll-shaped arms on its lower end, to force the clay through an aperturein the front of the mill into a press-box, wherein it is pressed inte moulds, placed by the operator underneath the said press-box. I l

Through the mill, horizontally, are run two stationarypipes, connected with the boiler. llhe portions of thesepipes which are inside themill are perforated, so that the lsteam from the boiler may enter the clay, and by the action of the knives or kneaders he thoroughly mingledA with it, thereby heating it, and by condensation softening and disintegrating andtempering the clay.

I construct my clayfmill of boiler-iron, or other suitable material, and with double walls, so as to form an annular chamber between the two walls which constitute the clay-mill, as shown by thedrawings. Around and v within this annular chamber I place a coiled tube, of such'diameter as not to divide the annular chamber into sections, or choke or prevent the free circulation of water with which the annular chamber is at all times to be kept full, in o'rder to supply the boiler, 'as well as .to furnish water, by means of suitable cocks, to' temper the clay.

Into the coiled tube is admitted steam vdirect from the boiler,by which means the water in the annular chamber surrounding the coiled tube is heated preparatory-to ventering the boiler, and the water required to temper theclay, in conjunction with the steam from the` perforated pipes, is also heated.

-By this arrangement my .clay-'mill also serves as a f heater, to prepare the water to enter the boiler,V and also heats the water to be used in tempering the clay, and, by its walls being themselves heated, serves to retain lthe heat imparted to the clay by the steam from the perforated pipes, in conjunctionrwith the hot water from the cocks.

'Portions of the sides of this annular chamber, opposite to each other, rise above the remainder of the sides like thehandles-of a wash-tub, and form -both the'support for the driving-shaft and'chambers for the water in the annular chamber to rise above the clay in the clay-mill, and are provided with suitable cocks, by which the water is allowed to fall over the clay" when steam alone is insulicient to temper the clay; thus, by employing heat, steam, and hotwater, the clay will be'niore thoroughly tempered, and the bricks`,`when moulded and delivered on the yard, will be quite warm, and by the radiation of the heat the bricks will dry in less time thun is usually required, consequently a great saving of time will be e'eeted in preparing the bricks for burning in the kiln. I

The following is av description of. the accompanying drawings.:

A is the boiler; B is the portable bed upon which the boiler A is placed; C is the steam-cylinder; D is the .tassa clay-mill, fitted-directly upon the boilerA, (the 1pum-p is .not shown inthe drawings.) E is the shaft, which runs through the clay-mill, and 'da are its knives on kneaders, for stirring the clay. b is. the -a'p erture in the front of the mill, through which theclay is forced by the nsu'alscroll-shaped arms on the lower end of tlie shaft E,

inta the press-box F, wherein itis pressed -into moulds, placed underneath said press-box bythe operatoxga before stated. c d are the inner and euterwalls o'fthe ,clay-mill, which'form the annular or water-chamber. G'. :is the spiral tube, runningaround the clay-mill in the annular water-chamber, linto which steam' is introduced fromthe boiler with which it is connected, for the'pnrpose'iof heating .the water in said annular chamber, as before stated, g g are the-portions of the sides of thevanular. chamber e, vwhich rise above the remainder-of the sides, and form both lthe supports for the driving-shaftsjand chambers Vfor the ,tvater in the annular chamber l*to rise above the clayin the clay-mill, and are: provided with suitable cocks, (not seen in `the drawings,) by

which the water is allowed to fall over th'e clay when steam alone is insuiicient to temper the clay, as hereinbefore described. H H are the stationary steam-pipes'connected with the 4boiler, whichrunthrough the claymill horizontally,` with that part ot .them inside the clay-millsopperiorat'ed lthat-'the steam from the boilermay enter the clay, and, by the action of thev knives or kneaders a a on the shaft E, be thoroughly`-mi'ngledwitliit, Vthereby -heating it, and byfeondensation softening and'disintegrating and tempering the clay, asbeforc stated.

What' I claim as my invention, and desire t'o secure by Letters Patent, s

1. A complete and portable .bricksmachinm composedof thefsteam-boiler A, cylinder 1C, clay-mill D, con-- structed as described, combined andarranged in one portable apparatus, in the manner and .for the purpose herein set forth; i p y 2. 'The formation of the annular chamber e of the clay-mill D, wziththeelevated chambersg g, the spiral steam-tube G, as connected with the boiler, and arranged in the'annular chamber E, and the stationary perforated steam-pipes H H, passing directly. from' the b'oiler'throughvthe clay-mill, horizontally, all combined in the manner and for the purpose herein set forth and described. v
